Reading from the Book of Isaiah 55:1-13
1 “Come, all you who are thirsty, come to the waters; and you who have no money, come, buy and eat! Come, buy wine and milk without money and without cost. 2 Why spend money on what is not bread, and your labor on what does not satisfy? Listen, listen to me, and eat what is good, and you will delight in the richest of fare. 3 Give ear and come to me; listen, that you may live. I will make an everlasting covenant with you, my faithful love promised to David. 4 See, I have made him a witness to the peoples, a ruler and commander of the peoples. 5 Surely you will summon nations you know not, and nations you do not know will come running to you, because of the LORD your God, the Holy One of Israel, for he has endowed you with splendor.” 6 Seek the LORD while he may be found; call on him while he is near. 7 Let the wicked forsake their ways and the unrighteous their thoughts. Let them turn to the LORD, and he will have mercy on them, and to our God, for he will freely pardon. 8 “For my thoughts are not your thoughts, neither are your ways my ways,” declares the LORD. 9 “As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. 10 As the rain and the snow come down from heaven, and do not return to it without watering the earth and making it bud and flourish, so that it yields seed for the sower and bread for the eater, 11 so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it. 12 You will go out in joy and be led forth in peace; the mountains and hills will burst into song before you, and all the trees of the field will clap their hands. 13 Instead of the thornbush will grow the juniper, and instead of briers the myrtle will grow. This will be for the LORD’s renown, for an everlasting sign, that will endure forever.”
The prophets were mouthpieces for God. They were called to speak God's words to people, situations, cities, dry bones, moutains, or whatever God told them to speak to. To full their God ordained mission, they had to be submitted to the Lord, and their mouths had to be consecrated to Him.
Those who desire to be used by God need to allow Him to deal with them concerning their mouths and the things they say. If you want Him to use you, be prepared for Him to deal with you concerning your words so that you are able to represent Him well with your mouth when the time comes for you to speak His Word.
As you wait on Him to show you what His desires are, open your ears to hear. Wait and listen.
